A wireless PAN isa PAN that is typically carried over a low-powered, short-range wirelessnetwork technology, such as Bluetooth, Zigbee, an infrared dataassociation (IrDA) communication protocol, or wireless universal serialbus (USB), among other examples. Bluetooth, for example, is apacket-based protocol with a master/slave architecture, in which amaster device may pair with and communicate with one or more slavedevices.

DETAILED DESCRIPTION

The following detailed description of example implementations refers tothe accompanying drawings. The same reference numbers in differentdrawings may identify the same or similar elements.

Short-range wireless communication technologies, such as near fieldcommunication (NFC), Bluetooth, Bluetooth low energy (BLE), or otherpersonal area network (PAN) protocols, may be used to allow wirelesscommunication between different electronic devices. In some cases,short-range wireless communication technologies may be used tofacilitate contactless transactions between a user device andtransaction terminals, such as point of sale (PoS) terminals, automatedteller machines (ATMs), or access terminals (e.g., locking mechanismsfor doors, gates, rooms, or safes), among other examples. Short-rangewireless communication capabilities of a user device, such as asmartphone, tablet, or wearable device, can typically be turned on andturned off by a user. For example, a user may turn off a short-rangewireless communication capability of a user device when the user deviceis not using the short-range wireless communication capability in orderto reduce power consumption by the user device. However, when theshort-range wireless communication capability of the user device isturned off, the user device cannot communicate with other devices viathe short-range wireless communication capability, and therefore, maynot be able to utilize services, such as contactless transactions,available via short-range wireless communication with other devices.

Some implementations described herein enable remote activations of ashort-range wireless communication capability of a user device via aremote activation signal. An activator device may transmit an activationsignal having a signal pattern, and the user device may receive theactivation signal. The user device may authenticate the activationsignal based on the signal pattern, and activate a short-range wirelesscommunication capability based on authenticating the activation signal.The user device may communicate with the activator device and/or anotherdevice using the short-range wireless communication capability based onactivating the short-range wireless communication capability. As aresult, the short-range wireless communication capability of the userdevice may be automatically activated in situations in which the userdevice may use the short-range wireless communication capability tocommunicate with other devices and/or access services available via theshort-range wireless communication capability. Thus, the user device maynot be prevented from utilizing a service or device pairing availablevia the short-range wireless communication capability when theshort-range wireless communication capability of the user device isleft, inadvertently or otherwise, in a deactivated state. Furthermore,this allows a user to leave the short-range wireless communicationcapability of the user device turned off when not being used, withoutthe user having to manually turn on the short-range wirelesscommunication capability or leave the short-range wireless communicationcapability turned on, thus reducing power consumption of the userdevice.

FIGS. 1A-1C are diagrams of an example 100 associated with activation ofshort-range wireless communication via a remote activation signal. Asshown in FIGS. 1A-1C, example 100 includes a user device, an activatordevice, and a pairing device. These devices are described in more detailin connection with FIGS. 2 and 3 .

As shown in FIG. 1A, and by reference number 105, the user device mayperform an initial pairing with the pairing device via a short-rangewireless communication protocol. For example, the user device and thepairing device may communicate via a PAN, such as Bluetooth, Zigbee,IrDA, or wireless USB, among other examples, or another short-rangewireless communications protocol, such as NFC. As shown in example 100,the user device may pair with and communicate with the pairing devicevia Bluetooth. Although implementations are described herein inconnection with activation of a Bluetooth capability of the user devicevia a remote activation signal, techniques described herein inconnection with FIGS. 1A-1C may be used for remote activation of otherPAN capabilities and/or other short-range wireless communicationcapabilities of the user device.

The user device may detect that the pairing device is within a range ofthe user device (e.g., a communication range or a communicativeproximity), and pair with the pairing device via Bluetooth to enableBluetooth communication between the user device and the pairing device.In some implementations, the user device may be a Bluetooth masterdevice and the pairing device may be a Bluetooth slave device. In someimplementations, the pairing device may be the Bluetooth master deviceand the user device may be the Bluetooth slave device. The initialpairing between the user device and the pairing device may be based onthe user device receiving a user input to pair with the pairing devicevia Bluetooth.

As further shown in FIG. 1A, and by reference number 110, the userdevice may receive a user input authorizing remote Bluetooth activationfor the user device. In some implementations, the user device may prompta user to indicate whether or not to authorize remote Bluetoothauthorization based on performing the initial pairing with the pairingdevice. The user may authorize remote Bluetooth activation for pairingwith the pairing device. In some implementations, the pairing device maybe one of multiple pairing devices in a remote activation system. Forexample, the remote activation system may include one or more PoSterminals, one or more ATMs, one or more access terminals, or one ormore wireless speakers, among other examples. In this case, the user mayauthorize remote Bluetooth activation for pairing with the pairingdevice or the user may authorize Bluetooth activation for pairing withany of the pairing devices in the remote activation system.

In some implementations, authorization of remote Bluetooth activationfor the user device may be performed independently of the initialpairing with the pairing device. For example, the user may set a settingof the user device to authorize remote Bluetooth activation for allBluetooth pairings. In some implementations, the user device may beconfigured with a default setting to allow remote Bluetooth activation.

As further shown in FIG. 1A, and by reference number 115, the userdevice and the activator device may synchronize signal patterns forremote Bluetooth activation. The activator device may be part of theremote activation system associated with the pairing device. In someimplementations, the activator device and the pairing device may beincluded in the same device. In some implementations, the activatordevice and the pairing device may be included in different devices. Theremote activation system may include one or multiple activator devicesand one or multiple pairing devices.

The activator device may transmit activation signals with time-varyingsignal patterns to cause the user device and/or other user devices toactivate a Bluetooth capability. In some implementations, the activatordevice may follow a schedule for varying the signal pattern of theactivation signal. For example, the activator device may switch thesignal pattern at regular or irregular time intervals. In this case, theactivator device may transmit, to the user device, informationidentifying the set of signal patterns used by the activator device anda respective timing associated with each signal pattern in the set ofsignal patterns. In some implementations, the timing may be a timeand/or duration for using each signal pattern relative to a current timeat which the synchronization is being performed. In someimplementations, the timing may be based on an absolute time, such asthe time of day. In this case, the user device and the activator devicemay synchronize to an external clock for determining the absolute time(e.g., based on a global positioning system and/or based onsynchronization signals from a wireless access point, such as a basestation, among other examples).

In some implementations, the activator device may determine a signalpattern to transmit at a particular time, and/or a duration for usingthe signal pattern, using an algorithm based on the current time (e.g.,based on an external clock). In this case, the activator device maytransmit, to the user device, information identifying the algorithm usedto determine the signal pattern based on the current time. In someimplementations, the activator device may transmit, to the user device,an indication of an initial signal pattern to be used to activate theBluetooth capability of the user device. In this case, once the initialsignal pattern is used to activate the Bluetooth capability of the userdevice, and the user device pairs with the pairing device again oranother pairing device in the remote activation system, the activatordevice may transmit a next signal pattern to be used to activate theBluetooth capability of the user device.

In some implementations, the activator device may transmit, to the userdevice, information that identifies time-varying signal patterns thatare specific to the user device (e.g., based on a user device identifierassociated with the user device). In some implementations, the activatordevice may transmit, to the user device, information that identifiestime-varying signal patterns to be broadcast by the activator device andto be received by the user device or any other device within a range ofthe activator device.

The activation signal may be any signal that can be transmitted using aparticular signal pattern or include information indicating a particularsignal pattern. In some implementations, the activation signal may be adigital signal transmitted via a wireless local area network, such as aWi-Fi network. In this case, the signal pattern may be a digital keyincluded in the activation signal. The digital key may be a numericsequence or a binary sequence, and the activator device may vary thedigital key over time. In this case, the activator device may transmit,to the user device, information identifying a time-varying set ofdigital keys to be used by the activator device. In someimplementations, the activator device may transmit an activation signalincluding a digital key via a short messaging service (SMS) message orvia a wide area network (e.g., a wireless wide area network), such as acellular network.

In some implementations, the activation signal may be an acousticsignal, and the signal pattern may be an acoustic signal pattern of theacoustic signal. In this case, the activator device may transmit, to theuser device, information identifying a time-varying set of acousticsignal patterns to be used by the activator device. In someimplementations, the activation signal may be a light signal, and thesignal pattern may be a light pattern. In this case, the activatordevice may transmit, to the user device, information identifying atime-varying set of light patterns to be used by the activator device.In some implementations, the activation signal may be a vibrationsignal, and the signal pattern may be a vibration pattern. In this case,the activator device may transmit, to the user device, informationidentifying a time-varying set of vibration patterns to be used by theactivator device.

As further shown in FIG. 1A, and by reference number 120, the userdevice may store information identifying the time-varying signalpatterns to be used by the activator device. For example, the userdevice may store, in a data structure, a set of signal patterns (e.g.,“Signal Pattern A,” “Signal Pattern B,” and “Signal Pattern C” in FIG.1A) and timing information (e.g., “t1,” “t2,” and “t3” in FIG. 1A)associated with the signal patterns. In some implementations, the userdevice may store information identifying an algorithm for determiningthe signal pattern at a particular time.

As shown in FIG. 1B, at a time subsequent to the initial pairing withthe pairing device, the Bluetooth capability of the user device may bedeactivated. For example, a user of the user device may have turned offthe Bluetooth capability of the user device and/or the Bluetoothcapability may have been deactivated for power saving. As shown byreference number 125, the activator device may detect a presence of theuser device. For example, the activator device may determine that theuser device is within a range of the activator device and/or a range ofthe pairing device (e.g., a communication range and/or communicativeproximity). In some implementations, the activator device may detect thepresence of the user device on a wireless local area network. In someimplementations, the activator device may detect the physical presenceof the user device or a user of the user device. For example, theactivator device may detect the physical presence of the user device ora user of the user device using one or more sensors, such as a proximitysensor, a motion sensor, a radar sensor, a light and detection ranging(LIDAR) sensor, and/or a vibration sensor.

As further shown in FIG. 1B, and by reference number 130, the activatordevice may transmit an activation signal, and the user device mayreceive the activation signal. In some implementations, the activatordevice may broadcast the activation signal, to be received by anydevices within the range of the activator device. In someimplementations, the activator device may transmit the activation signalin a transmission (e.g., via a wireless local area network or SMSmessage) that is specific to the user device. In some implementations,the activator device may transmit the activation signal based ondetecting the presence of the user device. For example, the activatordevice may broadcast the activation signal and/or transmit theactivation signal to the user device based on detecting the presence ofthe user device on a local area network. Additionally, or alternatively,the activator device may broadcast the activation signal based onsensor-based detection of the presence of an object (e.g., the userdevice, the user, or any other object) in the range of the activatordevice.

In some implementations, the activator device may transmit theactivation signal regardless of whether the user device (or anotherobject) is detected. For example, the activator device may periodicallytransmit the activation signal at a regular time interval. In this case,the activator device may or may not perform detection of the userdevice.

The activator device may include one or more output componentsconfigured to transmit the activation signal. In some implementations,the activator device may transmit the activation signal via a wirelesslocal area network, for example, using an antenna of the activatordevice. In this case, an antenna of the user device may receive theactivation signal. In some implementations, the activator device maytransmit an acoustic activation signal, for example, using one or morespeakers of the activator device. In this case, a microphone of the userdevice may receive the activation signal. In some implementations, theactivator device may transmit a light signal, for example, using a lightsource of the activator device. For example, the light signal may be alight signal in the visual spectrum or a light signal in the invisiblespectrum, such as an infrared light signal or an ultraviolet lightsignal. In this case, a light sensor of the user device may receive thelight signal. In some implementations, the activator device may transmita vibration signal, for example, using a vibration motor of theactivator device. In this case, a vibration sensor of the user devicemay receive the vibration signal, for example by sensing the vibrationson a surface that is in contact with the activator device.

The activator device may determine a signal pattern (e.g., digital key,acoustic signal pattern, light pattern, or vibration pattern) associatedwith activating Bluetooth in the user device, and may transmit theactivation signal with the determined signal pattern. For example, theactivator device may determine a current signal pattern of a set oftime-varying signal patterns based on a schedule for switching betweenthe signal patterns in the set of time-varying signal patterns. Asdescribed above, the activator device may synchronize the schedule forswitching between the signal patterns with the user device. In someimplementations, the activator device may determine the current signalpattern using an algorithm based on the current time.

As further shown in FIG. 1B, and by reference number 135, the userdevice may authenticate the received activation signal based on thesignal pattern in the received activation signal (referred to herein asthe “received signal pattern”). In some implementations, the user devicemay determine whether the received signal pattern (e.g., a first signalpattern) matches a stored signal pattern (e.g., a second signal pattern)associated with remote Bluetooth activation. The stored signal patternmay be a signal pattern indicated in information received from theactivator device, as described elsewhere herein (e.g., in connectionwith reference number 115 of FIG. 1A). For example, the user device maydetermine whether the received signal pattern matches a current signalpattern of a stored time-varying set of signal patterns based on thetiming information associated with the stored time-varying set of signalpatterns. In some implementations, the user device may determine areference signal pattern based on the current time using an algorithmreceived from the activator device, and determine whether the receivedsignal pattern matches the reference signal pattern.

In example 100 of FIGS. 1A-1C, the user device uses information receivedfrom activator device during synchronization to authenticate theactivation signal. In some implementations, the user device may performthe authentication without first performing the synchronization. Forexample, the activator device may communicate with a network device,such as a server, via a network. The network device may control theactivator device to vary the signal pattern, or the activator device maynotify the network device of the current signal pattern when theactivator device switches the signal pattern. The user device, forexample via an application executing on the user device, may communicatewith the network device and receive information that identifies thecurrent signal pattern from the network device. For example, the userdevice may request the current signal pattern from the network devicebased on receiving the activation signal from the activator device. Theuser device may authenticate the received activation signal bydetermining whether the received signal pattern is the same as thecurrent signal pattern received from the network device.

As shown in FIG. 1C, and by reference number 140, the user device mayactivate the Bluetooth capability. The user device may activate (turnon) the Bluetooth capability of the user device based on receiving andauthenticating the activation signal. In some implementations, the userdevice may activate the Bluetooth capability without notifying the userand/or without receiving any user input. In some implementations, theuser device may generate a notification to alert the user that Bluetoothhas been activated. For example, the user device may display a pop-upnotification on a display of the user device and/or play a soundnotification to alert the user that Bluetooth has been activated. Insome implementations, the user device may display a prompt that requeststhat the user approve the activation of Bluetooth. In this case, theuser device may activate the Bluetooth capability based on receivinguser input indicating that the user approves the activation ofBluetooth.

As further shown in FIG. 1C, and by reference number 145, the userdevice may communicate with the pairing device via Bluetooth. Forexample, the user device may automatically detect the pairing device andpair with the pairing device via Bluetooth based on activating theBluetooth capability. Once paired, the user device may communicate withthe pairing device via Bluetooth. In some implementations, the userdevice may communicate with the pairing device to perform a contactlesstransaction, such as a financial transaction (e.g., with a PoS terminalor an ATM), or to gain access to an access controlled entry via anaccess control terminal, among other examples.

Although implementations are described herein in connection withactivating Bluetooth or another short-range communication capability ofa user device, techniques described herein may be used to activate othertypes of communication capabilities of a user device. For example, insome implementations, an activator device may transmit, to a userdevice, an activation signal to cause the user device to activate acapability to communicate via a wireless local area network (e.g., aWi-Fi capability) or a cellular network. In this case, in addition tothe examples described above, the activator may transmit the activationsignal via a PAN, such as Bluetooth, NFC, or another short-rangewireless communication protocol. In some implementations, the activatormay transmit the activation signal using one type of short-rangewireless communication protocol (e.g., a first wireless communicationprotocol) to cause the user device to activate a capability tocommunicate using another type of short-range wireless communicationprotocol (e.g., a second wireless communication protocol).

Using the techniques described herein, a user device may activate ashort-range wireless communication capability based on receiving aremote activation signal transmitted by an activation device. Thus, theuser device may be enabled to use a service or device pairing availablevia the short-range wireless communication capability when theshort-range wireless communication capability of the user device isleft, inadvertently or otherwise, in a deactivated state. Furthermore,this allows a user to leave the short-range wireless communicationcapability of the user device turned off when not being used, withoutthe user having to manually turn on the short-range wirelesscommunication capability or leave the short-range wireless communicationcapability turned on, thus reducing power consumption of the userdevice.

As indicated above, FIGS. 1A-1C are provided as an example. Otherexamples may differ from what is described with regard to FIGS. 1A-1C.

In someimplementations, the transaction device may be a mobile device or may beintegrated into the mobile device. The transaction device may storeaccount information, which may be used in connection with an electronictransaction. The account information may include, for example, anaccount identifier that identifies an account (e.g., a bank account or acredit account) associated with the transaction device (e.g., an accountnumber, a card number, a bank routing number, and/or a bank identifier),a cardholder identifier (e.g., identifying a name of a person, business,or entity associated with the account or the transaction device),expiration information (e.g., identifying an expiration month and/or anexpiration year associated with the transaction device), and/or acredential (e.g., a payment token). In some implementations, thetransaction device may store the account information in tamper-resistantmemory of the transaction device, such as in a secure element. As partof performing an electronic transaction, the transaction device maytransmit the account information to a transaction terminal using acommunication component, such as a magnetic stripe, an integratedcircuit (IC) chip (e.g., a EUROPAY®, MASTERCARD®, VISA® (EMV) chip),and/or a contactless communication component (e.g., an NFC component, aradio frequency (RF) component, a Bluetooth component, and/or a BLEcomponent).
